Notes on this view:

This print was made on commercially manufactured blueprint paper intended for photographic use. Unlike high contrast blueprint paper produced for line drawings, such as those used to depict architectural plans, this paper was formulated to render the tonal gradations necessary for photographic printing.

The manufacturer of this particular paper is unknown. During the late 19th and early 20th centuries, several companies produced pictorial blueprint paper. French Satin Jr. by J.C. Millen was the self-proclaimed first, releasing their photographic paper in 1885. Other notable brands were Eastman’s Ferro-Prussiate Paper and E. & H.T. Anthony and Co.’s Ferroprussiate Paper.

Sensitized paper was highly susceptible to degradation by heat, air and moisture therefore companies distributed it in hermetically sealed metal tubes.
